> In NativeS3FileSystem if you do a copy of a directory it will copy all the
> files to the new location, but it will do this with one thread. Code is
> below. This jira will allow a configurable number of threads to be used to
> issue the copy commands to S3.
> do {
> PartialListing listing = store.list(srcKey, S3_MAX_LISTING_LENGTH,
> priorLastKey, true);
> for (FileMetadata file : listing.getFiles())
> { keysToDelete.add(file.getKey()); store.copy(file.getKey(), dstKey +
> file.getKey().substring(srcKey.length())); }
> priorLastKey = listing.getPriorLastKey();
> } while (priorLastKey != null);
